Bruce Willis Makes His Marriage Legal

After their wedding celebration in the Caribbean last weekend, the actor and the model/actress were wed in a civil ceremony Friday at a friend's house in Beverly Hills, his rep, Paul Bloch, tells PEOPLE. "They could not be happier," Bloch says.

The couple, who met through mutual friends, have been together for more than a year. They said their first "I do's" on March 21 in a small ceremony at Willis's home in Parrot Cay, Turks & Caicos, with his ex-wife Demi Moore and her husband Ashton Kutcher among the guests. – Mike Fleeman and Elizabeth Leonard
